I The invention relates to improvements in steam generators and an object of the inven .tion is to provide an a paratus whereby superheated steam can ex itiously and quickly generated and wherem water is reheated and then deposited'in drops or g obules on a hot plate, the drops being practically instantaneously converted into superheated steam which can be utilized as de sired.

A further object is to construct the device so that the quantity of steam generated can be readily controlled and. such that the heated water will be effectively broken up prior to impinging on thehot plate. a

With the above more im ortant and other minor objects in view w ich will becomemore apparent as the description proceeds, the invention consists essentiallym the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawings, in which v I A Fig. 1 is a side elevation of the generator,

15 the insulating casing being shown in vertical section. I Fig. 2 is a vertical sectional view centrally through the generator, certain parts belng shown in side elevation. 3 Fig. 3 is a horizontal sectional view at 3-3 Figure 2 and looking downwardly. Fig. 4-. is a vertical sectional view at 4-4 Figure 3. In thedrawings like characters of reference indicate'corresponding parts in the several figures.

The steam enerating chamber 1 of my de' vice is formed between two cupped or dished upper and lower lates 2 and 3 both of which are provided at t eir edges with outstanding marginal flan s 4 and 5 which are tightly fastened toget er by suitably spaced bolts 6,

a gasket 7 being interposed between the flanges'to insure of a steam tight joint. The upper plate is dished to a greater extent than the under plate, such forming a generatmg chamber which is substantially crescent shaped in vertical cross section. The lower plate is also supplied with a depending flange 8 and may have the upper face thereof provided with ribs 9 or may be plane surfaced as found most eficient.

Means is provided within the chamber for effectively breaking up the falling globules of water, such being herein shown as a screen 10 overlying the lower plate.

.Directly above the generating chamber, I locate a water heating drum indicated generallyby the reference numeral 11 and this drum 1s in the form of a cylindrical casing 12 havin top and bottom heads 13 and 14: and suitab y spaced tubes 15 connecting the heads, the tubes opening through the heads in the well known manner. A pipe 16 connects the interior of the drum with the interior of the generatin chamber and the said pipeis provided wit a valve 17 of any approved design controlling the flow of water therethrough. The valve is controlled by a valve rod 18 attached thereto and extending to the 7 side of the generator through the insulating casing later described.

A water tank 19 is su ported in any suitable manner from the dim bein connected to the upper end of the drum %)y a pipe 20 and the arrangement ofthe arts is such that the water in the tank feeds y gravity to the drum. The water tank is supplied with a sight glass 21' of any approved design so that the level of the water in the tank can be readily seen by the attendant and it is fitted at the top with a removable plug 22 through which water can be put into the tank as occasion demands. A pressure equalizing pipe 23 connects the generating chamber 1 with the top of the water tank and a pressure gauge 24 is utilized to indicate pressure of the steam in the generator. A steam supply pipe 25 leads from the upper plate of the generator and communicates with the generating chamber, this pipe being utilized to direct the generated steam to the point of use.

At the point where the pipe 16 enters the generating chamber, it is supplied. with a sprayer or distributor 26 adapted to distrib- 9 ute the water in a spray falling over the entire area of the lower plate 3 and the globules of water are further broken into smaller particles by the screen, such particles subsequently impinging on the bottom plate 3. 1M

proved desi Directly under the bottom plate, I locate a burner 27 such as a gas burner of any apsuch burner being adapted to heat the ormer late and the generating chamber to such a egree that as soon as the small particles of water strike the bottom plate 3, they will be immediately disintegrated and turned into steam which steam is led from the device through the steam .pi e25. In order to retain the heat, the drum an generating chamber are enclosed within an asbestos or such like outer casing 28 in'the well known manner. What I claim as my invention is In a steam generator, a closed generating chamber crescent shaped in vertical cross section and arranged when in operative position with the concave side facing downwardly, and having a steam pipe leading therefrom, a heater underlying the concaved under side of the generating chamber, a cylindrical water heating drum overlying the generatingchamber and having a plurality of heating pipes passlng upwardly therethrough, a valve controlled pipe connecting the bottom of the heating drum with the top of the chamber, a sprayer communicating with the pipe and positioned in the upper part of the chamber, means for supplying liquid to the heating drum and a cone shaped heat retaining casing enclosin the generating chamber and the heating rum.
